TURNER Foe HUE-CLEANERS.

Specification of Letters Patent.

Patented May 29, 1906.

Application led March 1.1904. Serial Noc 195,958.

To (if/ZZ whom, it may concern:

Be it known that I, CYRUs S. DEAN, a subject ofthe King of England, residing at Fort Erie, in the county of Velland, Province of Ontario, and Dominion of Canada, have inventeda new and useful Improvement in Turners for Flue-Cleaners, of which the following is a speciiication.

My invention relates to turners for Vfluecleaners, and more particularly to turners for flue-cleaners ofthe type known as the hammer)7 type.

rI'he object of my invention is to produce a slow but continuous automatic movement in rotation when the hammer is in action for the purpose of distributing the blows of the hammer equally over the interior surface of the iiue.

In the drawings herewith, Figure 1 is a longitudinal section taken through the axes of the working parts, showing my device applied to a hammer. Fig. 2 is a top plan view. Fig. 3 is a cross-section on the line :c of Fig. 1. Figs. 4, 5, 6, and 7 are views of a modiiied form of my invention, in which Fig. 4 is a top plan view. Fig. 5 is a longitudinal section at right angles thereto. Fig. 6 is a view looking from the right in Fig. 4. Fig. 7 is a section on the line y y of Fig. 4. Fig. 8 is a detail view ot my ratchet mechanism on. a larger scale.

I will iirst describe the construction shown Since the hammer is no part of my invention, the same need not be described further than to state that the driving-plate 1 is actuated. by the movement of the piston 2. Pivotally mounted within the body 3 of the turner is a worm 4. Rigidly mounted upon a non-rotating part 5 is a gear 6. Vhen the gear 6 is held rigid and the worm 4 is rotated, it is evident that the worm 4 will cause the body 3 and the body of the hammer directly connected therewith to rotate. I produce this rotation of the worm 4 in the following manner: Pivoted upon a pin 7, secured to the body 3, is a lever 8, which at its outer end has a pin 9, which projects upwardly and travels in a slot 10 in the driving-plate 1. This slot 10 is inclined slightly to the line of travel' of the drivingplate 1, so that the pin 9 is caused to move laterally and to reciprocate over a small arc of a circle the head 11 of the lever 8.

worm 4 is provided with a serrated or ratchettoothed head 12, and pivoted at 13 and 14 upon the lever S are dogs 15 and 16, which engage upon the serrated surface of the head 12.

The action is as follows: When the plate 1 has given reciprocatory movement by the action of the steam upon the piston, the inclined slot 10 will cause transverse movement of the pin 9, and consequently cause movement over a small arc of a circle of the head 11. This movement will cause the .two dogs 15 and 16 to come alternately in contact with the head 12 and alternately travel up upon the serrated surface oi said head-that is to say, movement of the pin 9 downwardly in the position of Fig. 3 will cause the dog 15 to travel up upon the head 12 and obtain a fresh bite upon the same, and the same movement will cause the dog 16 to press against the head 12 and tend to rotate it in the direction of the hands of a clock. Reverse movement wouldcall the dog 15 into play and cause the dog 16 to travel up upon the head and obtain a fresh hold. In this manner the worm 4 is rotated, and with it the entire body of the hammer is rotated, provided the gear 6 and its connecting parts are rigidly held.

I will now describe the modified form of construction shown in Figs. 4 to 7, inclusive. I employ a similar lever Sa, which is pivoted at 7 and which has a pin 9 engaging in a slot 10a. I employ a similar reciprocating driving-plate 1a, actuated in the same manner as above described. The part 17 is integral with the body of the hammer, and in this part the lever SEL is pivoted. Upon the nonrotating part 3 are mounted two ratchet or serrated surfaces 18 and 19, and mounted over the non-rotating parts and within these ratchets are two collars 20 and 21, which are secured to the non-rotating portion 17 by screws taking through slotted openings, so that said parts 2() and 21 have a limited movement in rotation. The lever 8a has an extension 22, which is seated loosely in a slot 23 of the plate 20, and the body of the lever 8a is in like manner seated loosely in a slot 24 of the plate 21. If now the lever 8 is moved upon its axis, it will cause a slight movement in rotation of the plates 2O and 21 in opposite directions from each other. Mount- The 1 ed upon said plate 2O is a dog 25, which engages the ratchet 18, and mounted upon the l plate 21 is a dog 26, which engages lthe ratchet 19. These dogs are held up to work by springs. It will now be evident that if the plate 1a is given reciprocatory movement the pin 9a will be moved back and forth in the slot 10a, and through such reciprocatory movement of the lever 8a the plates 20 and 21 will be given reciprocatory movement in opposite directions from each other. This will cause the dogs 25 and 26 to engage the ratchets 18 and 19 alternately and alternately to gain fresh hold upon said ratchets upon the reverse movement.

It will be seen that the general principles of constructions are the same in Figs. 4, 5, 6, and 7 as they are in Figs. 1, 2, and 3, and I do not wish to limit myself absolutely to the constructions shown and described.

Having thus described my invention and its method of operation, what I claim is 1. In a Hue-cleaner the combination with a non-rotary part and a rotary part provided with a hammer, of means for causing rotation of the part carrying the hammer, comprising a reciprocable plate actuated by the engine, an engine in said rotary part, a lever pivoted to said rotary part and reciprocated by said driving-plate, a worm, a ratchet mechanism for rotating said worm and actuated by said lever, a gear mounted upon said non-rotary part and engaging said worm, whereby said hammer is caused to rotate.

2. A flue-cleaner comprising the combination of a rotary part and a non-rotary part of an engine carried by said rotary part, a driving-plate actuated by said engine, a reciprocable lever actuated by said driving-plate, said lever being pivoted to said rotary part, a worm mounted upon said rotary part, a ratchet upon said worm, dogs pivoted to said reciprocable lever, and engaging said ratchet, said dogs heilig pivoted oppositely upon the head of said lever in such manner that when said lever is reciprocated in one direction, one dog will engage said ratchet and move it,

and the other will engage it to take a fresh bite, and upon the opposite movement of said lever the dog having obtained a fresh l bite moves said ratchet while the opposite u eating in a plane parallel with the axis of the machine, a reciprocable lever, a roller on said lever engaging in said inclined slot upon said reciprocable plate, said reciprocating lever being pivotedl to said rotary part, a worm pivoted in said rotary part, a ratchet on the head of said worm, dogs pivoted to said reciprocable lever and engaging said ratchet,

said dogs being pivoted to said lever diametrically opposite the pivot of said lever, and both dogs engaging upon the same side of said ratchet, a gear rigidly mounted upon said non-rotary part and engaging said worm, whereby the reciprocatory movement of said engine, through said reciprocable plate and said reciprocable lever causes alternate movement of said dogs, thus imparting movement in one direction of said rotary part.

4. In a flue-cleaner the combination with a non-rotary part, a rotary part provided with a hammer, and an engine for actuating said hammer, of means for causing the movement of said rotary part comprising a reciprocable plate provided with an inclined slot, a reciprocable lever pivoted to said rotary part, a roller on said lever engaging in said slot, dogs pivoted to said reciprocable lever, a worm on said rotary part, a gear mounted up on said non-rotary part engaging said worm, and a serrated or toothed head on said worm engaging said dogs.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
